Since yesterday I have this problem: sometimes, after some use, the sytem (Debian Squeeze) becomes a little unresponsive to mouse and keyboard (some clicks and keystrockes are lost). It is as if a "mute" key is always pressed.If I switch to console (ctrl-alt-F1), I see a cotinuous series of ^@^@^@. This stop and start if I press capslock.
I would test with xev to see if that can tell you whether the x-server receives something from the keyboard, but I have no guess as to the cause. My hope would be for xev to tell you that key XXXX is being pressed all the time, or something similar.
